Ingredients

5 Lb Yellow Onions
6 Tbsp Unsalted Butter
0.5 Cup Dry Sherry
10 Cups Beef Broth
4 Cups Chicken Broth
6 sprigs Fresh Thyme
2 count Bay Leaves
2 Lb Gruyère Cheese
2 count Baguette
1 Tsp Black Pepper
1 batch Kosher Salt

Instructions

Caramelize onions low and slow: Melt butter in a large Dutch oven over medium-low. Add onions with salt and cook, stirring every few minutes, until deeply golden brown and jammy, 45–60 minutes — do not rush over high heat or they burn before sweetening. The pot should smell sweet, not acrid.
Deglaze and add stock: Stir in sherry, scraping browned bits. Simmer until almost dry, 2–3 minutes. Add beef broth, chicken broth, thyme, bay leaves, and pepper. Bring to a simmer and cook 20 minutes. Broth should taste rich and onion-sweet; consistency is thin soup, not gravy.
Toast baguette rounds: Arrange baguette slices on sheet pans. Toast at 400°F until dry and lightly golden, 8–10 minutes — dry bread floats and soaks broth without turning mushy. Hold at room temp up to 4 hours.
Fill crocks and top with cheese: Heat broiler with rack 6 inches from element. Ladle hot soup into oven-safe bowls or crocks, leaving ½ inch headspace. Float 2–3 baguette crouton rounds per bowl and blanket with Gruyère — cheese should cover croutons to the rim so it melts into a solid cap.
Broil the cheese cap and serve: Broil until cheese bubbles and browns in spots, 3–5 minutes — watch constantly, no distracted tones during this step. Serve immediately with extra pepper at the line. Hold finished crocks in a warm box up to 20 minutes; re-broil 1 minute if cheese sets.

Tonight's spread

Keep the pot on low simmer on the stove — ladle from the side so the bottom doesn't scorch.
Set shredded cheese, crackers, and hot sauce in a row beside the pot.
Line up French Onion Soup for the Hall on the main counter with serving spoons — firefighters grab fast between calls.
Keep a backup tray warm in the oven at 200°F for late arrivals after a run.

Hall tips

Keep a backup tray warm in the oven for late calls — nothing worse than cold plates after a run.
Taste for salt at the end — hall palates run salty after long shifts.

Substitutions

Ground turkey swaps 1:1 for beef in chili if the crew wants leaner.

Leftovers

Cool leftovers in shallow containers within two hours — deep pots stay hot too long.
Label trays with date and reheat to 165°F minimum before second shift.
Add a splash of stock or water when reheating — thick sauces tighten in the fridge.
